VC获取操作系统版本信息

OSVERSIONINFO osvi;                                                                        //定义OSVERSIONINFO数据结构对象
memset(&osvi, 0, sizeof(OSVERSIONINFO));                                  //开空间
osvi.dwOSVersionInfoSize = sizeof (OSVERSIONINFO);              //定义大小
GetVersionEx (&osvi);                                                                         //获得版本信息
m_dwMajorVersion=osvi.dwMajorVersion;                                    //主版本号
m_dwMinorVersion=osvi.dwMinorVersion;                                    //副版本
m_dwBuildNumber=osvi.dwBuildNumber;                                    //创建号
m_dwPlatformId=osvi.dwPlatformId;                                               //ID号
UpdateData(FALSE);
